It held 8 images at resolution 640 x 480, was fixed-focus, connected only to a Mac (an…d it didn't have media cards--you had to connect the camera to a computer to get the pictures off), and cost $750. The reaction was very simple: "You want $750 for THAT? No freakin' way!" On the professional side, we had Better Light backs for view cameras. They cost $35,000 and had to be tethered to a computer in use. They were also "scanning" backs.
